Analog Devices ADM1072

The ADM1072 is a logic controlled, dual P-channel switch with low on resistance and a built-in current limiter, capable of sourcing up to 1A from supply voltages between 2.7V and 5.5V. This allows the system power supply to be protected against short-circuits and surge currents in peripheral USB devices powered via the ADM1072. The ADM1072 also offers low quiescent current of typically 50µA and shutdown current of typically 10nA.

APPLICATIONS

Desktop Computers Palmtop Computers Notebook Computers Hand-Held Instruments Universal Serial Bus (USB) 1A MAIN FET In addition to logic inputs that switch each channel on and off, the device has a standby input that switches the output current limit, making it ideal for use with USB peripherals. In normal operating mode and Standby mode the output current is typically limited to 500mA and 100mA respectively, as outlined by the USB2.0 Specification. Over-current and over-temperature conditions are signalled by a fault output (FLT) for each channel.
